If there is a large growth on the body and pus from the large bag, it should be diagnosed as an abscess cavity, which is distributed superficially, and the first department to consult should be general surgery. In this case, some auxiliary tests should be performed, including routine blood tests to see if the white blood cells are elevated and if there is any co-infection, and superficial ultrasonography to clarify the size and location of the abscess cavity as well as its internal structure. If the abscess cavity is relatively superficial, a simple surgical procedure may be performed to incise the cavity, drain the pus by drainage, and then treat the wound with prophylactic antibiotics, either intravenously or orally, which is relatively appropriate. If the size of the abscess cavity is relatively large, or the location is relatively deep, or there are internal segregation, adhesions, or the patient has a combination of diabetes mellitus or some other diseases that affect immunity. In this case, the risk of surgery is a little higher, and may require hospitalization, surgery under relevant monitoring, to clean the pus cavity of pus, and then surgical sutures, while paying attention to monitor the skin healing, blood sugar, and use of antibiotics, and then after the wound is completely healed, the wound sutures will be removed, and then the patient can be discharged from the hospital.
